Field mapping connects columns in your CSV file to fields in Slant. Correct mapping ensures your data lands in the right place.

How mapping works

When you upload a CSV, Slant:
  1. Reads your column headers
  2. Attempts auto-mapping based on common names
  3. Shows you the proposed mapping
  4. Lets you adjust as needed

Mapping interface

For each column in your file:

StatusMapped, unmapped, or skipped

Standard field mappings

Person fields

Handling special cases

Date formats

Slant accepts multiple date formats:
FormatExample
YYYY-MM-DD2024-03-15
MM/DD/YYYY03/15/2024
DD/MM/YYYY15/03/2024
Month DD, YYYYMarch 15, 2024
For best results, use YYYY-MM-DD format. This avoids ambiguity between MM/DD and DD/MM.

Phone number formats

Slant normalizes phone numbers. These all work:
  • (555) 123-4567
  • 555-123-4567
  • 5551234567
  • +1 555 123 4567

Tier values

Map tier values to Slant’s system:
Your valueMaps to
A, Tier A, 1, PlatinumA tier
B, Tier B, 2, GoldB tier
C, Tier C, 3, SilverC tier
D, Tier D, 4, BronzeD tier

Boolean values

For yes/no fields:
Your valueMaps to
Yes, Y, True, 1True
No, N, False, 0False
(empty)Not set

Multiple values

Multiple emails

If a person has multiple emails: Option 1: Separate columns
first_name,email_1,email_2
John,[email protected],[email protected]
Option 2: Primary only Import the primary email, add others manually later.

Multiple phones

Similar to emails:
first_name,home_phone,mobile_phone,work_phone
John,555-111-1111,555-222-2222,555-333-3333

Multiple addresses

For multiple addresses, import the primary address. Add additional addresses manually after import.

Custom field mapping

Map to existing custom fields

If you’ve created custom fields in Slant:
1

Find your column

Locate the column in the mapping interface.
2

Open field selector

Click the target field dropdown.
3

Find custom fields

Scroll to “Custom Fields” section.
4

Select field

Choose your custom field.

Create custom fields during import

If you need a new custom field:
  1. Complete the current import without that column
  2. Create the custom field in settings
  3. Import again with just that column, updating existing records

Skip columns

Not every column needs to be imported:
1

Find the column

Locate the column to skip.
2

Select Skip

In the target field dropdown, choose “Skip this column.”
3

Column ignored

Data from this column won’t be imported.

When to skip

Skip columns that:
  • Contain internal IDs from other systems
  • Have data you don’t need in Slant
  • Duplicate information in other columns
  • Contain notes you’ll add differently

Auto-mapping

How auto-mapping works

Slant recognizes common column names:
  • “First Name” → person.first_name
  • “Email” → person.email
  • “Phone” → person.phone

Verify auto-mapping

Always check auto-mapped fields:
  1. Review each mapping
  2. Check sample data looks correct
  3. Adjust any incorrect mappings
Auto-mapping is a starting point, not a guarantee.

Troubleshooting mapping

Column not recognized

If Slant doesn’t auto-detect a column:
  1. Manually select the target field
  2. Or rename the column header in your CSV to match common names

Data appears wrong in preview

If mapped data looks incorrect:
  • Check you selected the right field
  • Verify data format matches expectations
  • Look for encoding issues (special characters)

Can’t find the right field

If the Slant field you need doesn’t appear:
  • Check you’re importing the right record type
  • The field may need to be created as a custom field
  • Some fields are read-only and can’t be imported

Mapping resets

If your mapping disappears:
  • Don’t navigate away during mapping
  • Complete the import in one session
  • If page reloads, you may need to re-upload

Save mapping templates

For recurring imports with the same structure:
1

Complete mapping

Set up all column mappings.
2

Save template

Click Save mapping as template.
3

Name template

Give it a descriptive name.

Use a saved template

1

Upload file

Upload your CSV as usual.
2

Apply template

Click Use saved mapping.
3

Select template

Choose your saved mapping.
4

Verify

Confirm mapping is still correct.

Best practices

Name columns clearly

Use unambiguous names:
  • ✓ “First Name” not “Name 1”
  • ✓ “Home Phone” not “Phone”
  • ✓ “Work Email” not “Email 2”

Check sample data

For each mapping, verify:
  • Sample data looks correct in preview
  • No obviously mismatched data
  • Formatting is recognized

Document your mappings

Keep a record of how you mapped fields, especially for:
  • Non-obvious mappings
  • Custom field usage
  • Skipped columns and why
