There are two values in gam.cfg that can be used to filter the input from gam csv commands.

• csv_input_row_filter - A list or JSON dictionary used to include specific rows based on column values
• csv_input_row_drop_filter - A list or JSON dictionary used to exclude specific rows based on column values

These filters can be used alone or in conjunction with the matchfield|skipfield <FieldName> <RegularExpression> options.

        "{\"<FieldNameFilter>\": \"<RowValueFilter>\"(,\"<FieldNameFilter>\": \"<RowValueFilter>\")*}"

Name:value form.

<RowValueFilterList> ::=
        "'<FieldNameFilter>:<RowValueFilter>'(,'<FieldNameFilter>:<RowValueFilter>')*"

• <RowValueFilterList>, even if it has one element, should be enclosed in ".
• Each <FieldNameFilter>:<RowValueFilter> pair should be enclosed in '.
• If <FieldNameFilter> contains a : or a space, it should be enclosed in \".
• If <RegularExpression> or <DataSelector> in <RowValueFilter> contain a space, it should be enclosed in \".
• If <FieldNameFilter> or <RegularExpression> in <RowValueFilter> contain a \ to escape a special character or enter a special sequence, enter \\\ on Linux and Mac OS, \\ on Windows,

Examples:

csv_input_row_filter "'\"accounts:used_quota_in_mb\":count>15000'"
csv_input_row_filter "'email:data:\"csvfile gsheet:email [email protected] FileID Sheet1\"'"
Linux and Mac OS
csv_input_row_filter "'phones.\\\d+.value:regex:(?:^\\\(510\\\) )|(?:^510[- ])\\\d{3}-\\\d{4}'"
Windows
csv_input_row_filter "'phones.\\d+.value:regex:(?:^\\(510\\) )|(?:^510[- ])\\d{3}-\\d{4}'"

JSON form.

<RowValueFilterJSONList> ::=
        '{"<FieldNameFilter>": "<RowValueFilter>"(,"<FieldNameFilter>": "<RowValueFilter>")*}' |
        "{\"<FieldNameFilter>\": \"<RowValueFilter>\"(,\"<FieldNameFilter>\": \"<RowValueFilter>\")*}"

• The first JSON form can be used on Linux and Mac OS; it can not be used on Windows.
• The second JSON form can be used on Linux, Mac OS and Windows.
• If <FieldNameFilter> contains a : or a space, no additional quoting is required

Example:

csv_input_row_filter '{"accounts:used_quota_in_mb": "count>=150"}'
csv_input_row_filter "{\"accounts:used_quota_in_mb\": \"count>=150\"}"

Row filtering includes/excludes rows based on column values.

Field names are specified by regular expressions; at its simplest, you specify a complete field name. Field names are matched in a case insensitive manner.

If the field name doesn't contain any of the following regular expression characters ^$*+|$[{(, it will be surrounded with ^$ so that it doesn't match any subfields that begin with the field name as a prefix.

The following filter will match the count field and not the subfields.

config csv_input_row_filter "'externalIds:countrange=1/10'"

primaryEmail,externalIds,externalIds.0.type,externalIds.0.value,externalIds.1.type,externalIds.1.value,...

You can include rows for gam csv commands based on column values. You specify a list of fields(headers) and the values they must have. csv_input_row_filter is used to specify the fields and values. Each field name/expression can appear only once in the list.

You specify whether all or any value filters must match for the row to be included in the input.

• csv_input_row_filter_mode allmatch - All value filters must match for the row to be included in the input; this is the default
• csv_input_row_filter_mode anymatch - Any value filter must match for the row to be included in the input

gam config csv_input_row_filter <RowValueFilterList> ...
gam config csv_input_row_filter <RowValueFilterJSONList> ...

You can exclude rows for gam csv commands based on column values. You specify a list of fields(headers) and the values they must not have. csv_input_row_drop_filter is used to specify the fields and values. Each field name/expression can appear only once in the list.

You specify whether all or any value filters must match for the row to be excluded from the input.

• csv_input_row_filter_drop_mode allmatch - If all value filters match, the row is excluded from the input
• csv_input_row_filter_drop_mode anymatch - If any value filter matches, the row is excluded from the input; this is the default

gam config csv_input_row_drop_filter <RowValueFilterList> ...
gam config csv_input_row_drop_filter <RowValueFilterJSONList> ...

A filter matches if the field has the desired value. lf you specify a regular expression for a field name that matches several columns, the filter matches if any of the columns has a match. In the case of notregex|notregexcs|notdata, the filter matches if none (not any) of the columns has a match.

<RowValueFilter> allows specifying that the filter will match only if all of the columns have a match. In the case of notregex|notregexcs|notdata, the filter matches if some (not all) of the columns have a match. If neither any or all is explicitly specified, any is the default.

These are the row value filter types:

• boolean:<Boolean> - Used on fields with Boolean values; a blank field is considered False
• count<Operator><Number> - Used on fields with numbers; a blank field will not match
• countrange=<Number>/<Number> - Used on fields with numbers; a blank field will not match
  • The field value must be >= the left <Number> and <= the right <Number>
• countrange!=<Number>/<Number> - Used on fields with numbers; a blank field will not match
  • The field value must be < the left <Number> or > the right <Number>
• data:<DataSelector> - Used on fields with text; field value must match some value in <DataSelector>; case sensitive
• date<Operator><Date> - Used on fields with dates or times; only the date portion of a time field is compared; a blank field will not match
• daterange=<Date>/<Date> - Used on fields with dates or times; only the date portion of a time field is compared; a blank field will not match
  • The field value must be >= the left <Date> and <= the right <Date>
• daterange!=<Date>/<Date> - Used on fields with dates or times; only the date portion of a time field is compared; a blank field will not match
  • The field value must be < the left <Date> or > the right <Date>
• length<Operator><Number> - Used on fields with strings; non string fields will not match
• lengthrange=<Number>/<Number> - Used on fields with strings; non string fields will not match
  • The field length must be >= the left <Number> and <= the right <Number>
• lengthrange!=<Number>/<Number> - Used on fields with strings; non string fields will not match
  • The field length must be < the left <Number> or > the right <Number>
• notdata:<DataSelector> - Used on fields with text; field value must not match any value in <DataSelector>; case sensitive
• notregex:<RegularExpression> - Used on fields with text; field value must not match <RegularExpression>; case insensitive
• notregexcs:<RegularExpression> - Used on fields with text; field value must not match <RegularExpression>; case sensitive
• regex:<RegularExpression> - Used on fields with text; field value must match <RegularExpression>; case insensitive
• regexcs:<RegularExpression> - Used on fields with text; field value must match <RegularExpression>; case sensitive
• text<Operator><String> - Used on fields with text
• textrange=<String>/<String> - Used on fields with strings
  • The field value must be >= the left <String> and <= the right <String>
• textrange!=<String>/<String> - Used on fields with strings
  • The field value must be < the left <String> or > the right <String>
• time<Operator><Time> - Used on fields with times; a blank field will not match
• timeofdayrange=<Hour>:<Minute>/<Hour>:<Minute> - Used on fields with times; a blank field will not match
  • The field value must be >= the left <Hour>:<Minute> and <= the right <Hour>:<Minute>
• timeofdayrange!=<Hour>:<Minute>/<Hour>:<Minute> - Used on fields with times; a blank field will not match
  • The field value must be < the left <Hour>:<Minute> or > the right <Hour>:<Minute>
• timerange=<Time>/<Time> - Used on fields with times; a blank field will not match
  • The field value must be >= the left <Time> and <= the right <Time>
• timerange!=<Time>/<Time> - Used on fields with times; a blank field will not match
  • The field value must be < the left <Time> or > the right <Time>

In versions prior to 5.12.00, regex:<RegularExpression> and notregex:<RegularExpression> were processed in a case sensitive manner; in many cases this is probably not desirable; e.g., matching file names which are case insensitive.

Now, regex:<RegularExpression> and notregex:<RegularExpression> are processed in a case insensitive manner. To get the prior case sensitive processing, use regexcs:<RegularExpression> and notregexcs:<RegularExpression>.

You want to process groups with 100 or more direct members.

gam redirect csv GroupInfo.csv print groups fields directmemberscount
gam config csv_input_row_filter "'directMembersCount:count>100'" csv GroupInfo.csv gam group "~email" ...

You want to process groups not created by an administrator.

gam redirect csv GroupInfo.csv print groups fields admincreated
gam config csv_input_row_drop_filter "'adminCreated:boolean:true'" csv GroupInfo.csv gam group "~email" ...

You want to process users created in the last 30 days.

gam redirect csv UserInfo.csv print users fields creationtime
gam config csv_input_row_filter "'creationTime:date>=-30d'" csv UserInfo.csv gam user "~primaryEmail" ...

You want to process users that are consuming more than 15GB of storage. Special quoting is required because the field name contains a colon.

gam redirect csv UserInfo.csv report user services accounts fields "accounts:used_quota_in_mb"
gam config csv_input_row_filter "'\"accounts:used_quota_in_mb\":count>15000'" csv UserInfo.csv gam user "~primaryEmail" ...

You can limit the number of rows read from a CSV file.

You want to process the first 10 users that are consuming more than 15GB of storage. Special quoting is required because the field name contains a colon.

gam redirect csv UserInfo.csv report user services accounts fields "accounts:used_quota_in_mb"
gam config csv_input_row_filter "'\"accounts:used_quota_in_mb\":count>15000'" csv_input_row_limit 10 csv UserInfo.csv gam user "~primaryEmail" ...

If you define a value for csv_input_row_filter, csv_input_row_drop_filter or csv_input_row_limit in the [DEFAULT] section of gam.cfg, it will apply to every gam csv command which is probably not desirable. You can store them in gam.cfg in named sections.

[Filter510]
csv_input_row_filter = 'phones.\\\d+.value:regex:(?:^\\\(510\\\) )|(?:^510[- ])\\\d{3}-\\\d{4}'

You want to process users with phone numbers in the area code 510; the number can be in the format (510) ddd-dddd or 510-ddd-dddd or 510 ddd-dddd.

gam redirect csv UserInfo.csv print users fields name,phones
gam selectinputfilter Filter510 csv UserInfo.csv gam user "~primaryEmail" ...

Version 6.30.00 added the gam comment <String>* command that can be used to validate input row filters.
